Mail Model, by Paraparaumu artist Rachel Goodman, took about 120 hours and a thousand stamps to complete.
Response to the piece has been mixed. "People either really love it or really hate it," Goodman said. The stamps - some dating back to pre-decimal days - brought back memories for some.
"People will look at a stamp and remember what they were doing or how old they were."
Show director Carla Russell said all art in the show was priced between $100 and $5000, with an average price of $500 to $600.
